The ANTARES undersea neutrino telescope consists of a 3D grid of 900 photomultiplier tubes arranged in 12 strings, at a depth of 2475 m in the Mediterranean Sea. After deployment of the first strings in 2006, half of the detector is now fully operational and the complete detector is foreseen to be finished in early 2008. Relic neutralinos produced after the Big Bang are favoured...

Cosmic Rays and UHECR are reaching highest energy well above LHC ones. Because photopion production they might hide UHE GZK neutrino that may airshower at Earth Horizons. These Airshowers mostly are Tau induced ones. SUSY traces might be also searched inside the same UHECR shower occuring on Earth. Indeed UHE neutralino and other surprising SUSY secondaries may offer a novel Astronomy at...

We make an improved analysis on the flow of neutrinos originating from WIMP annihilations inside the Sun and the Earth. We treat both neutrino interaction and oscillation effects in a consistent framework. Our numerical simulations are performed in an event based setting, which is useful for both theoretical studies and for creating neutrino telescope Monte Carlos. We find that the flow...

270. Reflection of Microwave from Energy Deposit by X-ray Irradiation in Rock Salt: Implying Salt Ultra High Energy Neutrino Detector to act like a Radio Bubble Chamber

We found microwave reflection from a small rock salt samples irradiated by X-ray. The reflection rate was consistent with number of ionized electrons by the irradiation. Coherent reflection was indicated by time dependence of the reflection rate. It means the irradiated size could be scaled up to ultra-high energy electromagnetic shower using longer wavelength while the reflection rate is...

335. Long lived staus in IceCube from atmospheric neutrinos

Parallel Talk

The discovery of a long-lived charged particle at future colliders can point towards scenarios where the dark matter (DM) particle is superweakly interacting, and the next-to-lightest particle (NLP) is charged and quasi-stable. Such a situation is expected in several supersymmetric models, including gauge mediation and even minimal supergravity, where the DM particle is the gravitino and...

396. Indirect dark matter search with H.E.S.S.

The annihilations of WIMPs produce high energy gamma-rays in the final state. These high energy gamma-rays may be detected by IACTs such as the H.E.S.S. array of Imaging Atmospheric Cherenkov telescopes. Besides the popular targets such as the Galactic Center or the galaxy cluster as M87, dwarf Sphreroidal galaxies are privileged targets for searching a Dark Matter annihilation...
